Timing Charts INPUT FUNCTIONS UP and DOWN Counters Preset and totalizing counters have DIP switch selectable counting direction. The graphs below show gate input for count interruption. The following timing charts combine operations of both single preset and double preset counters. For single preset counters, refer to the 2nd control output. "A" shows the count input minimum pulse width. If the count input is less than minimum pulse width, a miscount occurs and the count total will be ±1 count. UP Counting CP1: Count input, CP2: Gate input DOWN Counting CP1: Count input, CP2: Gate input Gate Gate Count value Count value CP1: Gate input, CP2: Count input CP1: Gate input, CP2: Count input Gate Gate Count value Count value Reversible Counters "A" shows the count input minimum pulse width. "B" must be greater than or equal to half the signal or a miscount will occur. In modes C and F, maximum input frequency should equal to CP1 + CP2.

COUNT AND RESET INPUT CONNECTIONS Contact inputs Connect CP1 count input contact between terminals 11 and 12, CP2 count input contact between terminals 9 and 12, respectively. Use a high-reliability contact capable of making and breaking 2.5 ma at 12 VDC. Connect a resistor rated at 680 Ω, 1/2 W between each input terminal and terminal 8 to increase reliability. Solid-state inputs Connect CP1 count input signal voltage between terminals 8 and 11, CP2 count input signal voltage between terminals 8 and 10, and a reset input signal voltage between terminals 8 and 9, respectively. Polarity of terminal 8 becomes (-) common. Signal voltage level of solid-state input When an input signal is applied to the counter at supply voltage E (V) from the load resistance (output resistor R (kω) of the transistor Tr in the solid-state circuit, input signal voltage level V becomes high when transistor Tr turns OFF. This "H" level can be calculated by the following equation: 4.7 E H level of V = (V) 4.7 + R Determine the value of R or E properly so that the result of the above equation stays within 5 to 30 V. In the following diagram, the "L" level of input signal voltage V is governed by the saturation voltage between the collector and emitter of transistor Tr. Generally, the saturation voltage of semiconductor is 1 V or less and the "L" range of 0 to 2 V may be adequately satisfied. Never apply an input signal at a voltage of 30 V or more. Avoid applying a reverse voltage. POWER SUPPLY CONNECTIONS Connect the required supply voltage to terminals 1 and 2. AC power supply DC power supply Full supply voltage must be applied all at once to the counter from switches or relays. Gradual application of supply voltage may cause non-power reset or memory change. When applying a power-off reset, be sure to provide a reset signal time (power-off time) longer than 0.5 sec. 12 to 24 VDC 48 VDC 100 VDC POWER SUPPLY FOR EXTERNALLY CONNECTED EQUIPMENT counters have a built-in power supply for externally connected components such as sensors for count or reset input, or loads connected to the solidstate control output (12 VDC, 80 ma). Power can be applied to sensors and loads simultaneously. Single preset counters Double preset counters 9

Open the front cover to expose the access screw on the lower right side. The internal unit can be drawn out by loosening the access screw. This allows the counter to have specifications changed without rewiring. 11
FUNCTION SELECTIONS MADE BY INTERNAL DIP SWITCHES To program the function specifications, set the rotary DIP switches and slide switches mounted on the PC board located at the right side of the internal unit (when viewed from the front). In the case of the "-M" type counters, with backup power supply function for memory protection, the new count value set by the thumbwheel switch or changes to the counting functions and operation modes by the DIP switches become effective only when the counter is reset by external or manual reset, but not by automatic reset. -2D, -2DM SW4 1 2 3 SW2 SW2 Output mode Switch Operation 0 N 1 F 2 C 3 R 4 K 5 P 6 Q 7 N 8 N 9 F A C B R C K D P E Q F N SW4-1 Solid-state output level SW4-2 Manual reset SW4-3 UP/DOWN UP (addition) counting DOWN (subtraction) counting -E2D, -E2DM SW1 SW1 Count input function selector SW4 1 2 SW2 Switch Input 0 A (command inputs L H) 1 A (command inputs L H) 2 B (individual inputs L H) 3 C (quadrature inputs L H) 4 D (command inputs H L) 5 D (command inputs H L) 6 E (individual inputs H L) 7 F (quadrature inputs H L) 8 A (command inputs L H) 9 A (command inputs L H) SW2 Output mode Switch Operation 0 N 1 F 2 C 3 R 4 K 5 P 6 Q 7 N 8 N 9 F A C B R C K D P E Q F N SW4-1 Solid-state output level SW4-2 Manual reset 12

Installation MOUNTING The illustrations at right show how to mount the counter in a panel with the Y92H-5 mounting brackets supplied with each unit. Insert the counter through the panel. Loosen the screw on the bracket, then insert the bracket in the slot on the bottom of the counter. Tighten the screw until it makes a clicking sound. Repeat the process with the top bracket. Y92H-5 bracket Y92H-5 bracket CAUTIONS REGARDING POWER SUPPLY, INPUT AND OUTPUT SIGNALS Allow 50 ms after power application for the voltage rise time in the internal circuit. The counter may not operate in response to signals input during this period. In the case of a momentary power failure, counters without backup power supply operate as follows depending upon the length of the power outage: Counters with memory protection (-M types) may respond to input signals during 50 ms after the power is turned off (or after power failure) since this period is the voltage fall time in the internal circuit. Power failure Action when power is duration restored 0.5 sec or more Counter is reset 0.01 sec or less Status before power failure is retained 0.01 to 0.5 sec Operation is unstable, either one is possible RESET AND THE DISPLAY While the reset signal (external or manual) is being applied, the digital display is extinguished in all digit positions and the reset LED indicator lights to show the reset input signal is being applied. When a reset is completed, the reset value is displayed on the digital display. Totalizing counters do not have a reset indicator. In output operation modes C, K, P, and Q, operations that cause the set time to be up twice within the one-shot time are not recommended. In output mode C, the internal counting circuit is reset at the same time as when the set count is up. For this reason, the up count value is not displayed. Counters with memory back-up (-M type) do not have a power reset function, so care must be taken in the following situations: When power is applied to the counter for the first time, the counter must be reset by applying external or manual input. If the internal specifications are changed during a power failure, the counter must be reset externally or manually after the power is restored. Failure to apply the reset will cause the counter to operate with the previous settings. If the set value is changed during a power failure, the counter need not be reset after power recovery. The back-up battery lasts about 10 years in normal use, but cannot be replaced. SETTINGS Do not reset thumbwheel switches while the counter is operating. Do not set both presets of a double preset counter to the same value. Do not allow the thumbwheel setting fall between numbers as the counter will ignore that digit and give a possible wrong count value. When the count value is all zeroes, there will be a momentary control output upon power application. This can be used to check normal output. 530 is how the counter will interpret this setting 0000 causes a momentary output 18
TESTING When conducting dielectric test, impulse voltage test, insulation resistance test, etc., between the electric circuit and the non-current-carrying metal parts with the counter mounted on the control board, remove the internal unit to isolate it from the counter circuit. Removal of the internal unit is necessary to prevent it from being damaged by the test voltage flowing across the power supply terminals of the counter, if some of the components mounted on the control board have insufficient dielectric strength or insulation resistance.
